how many gram of h2 needed to react with 3.10 n2
PHYSICS
The only force acting on a particle is conservative force F. If the particle is at point A, the potential energy of the system associated with F and the particle is 39 J. If the particle moves from point A to point B, the work done on the particle by F is +25 J. What is the po...

Math
I think I figure it out. The answer is: 12 A ^2 * 2 A * - 31 + 4 A * 6 + / I figured that that the square sign and the number 2 count as one operator. For ^2 I just use the x^2 button on the calculator and it gave me the same answers.

I need to change this expression to postfix form. (12*A^2-2*A+31)/(4*A+6) I know how to do this except for the squaring part. I got stuck. This is my try. 12 A 2 ^ * 2 A * - 31 + 4 A * 6 + / When I test this in a calculator, it gives different results. Another problem is that ...
